Talkers and listeners
Only one talker (output device) can be connected to a serial input (RX) on the unit, in
accordance with the NMEA0183 protocol. However, an output port (TX) on the unit may be
connected to up to three listener (receiver) devices, dependent on the hardware capabilities
of the receiver.
Ethernet
The Ethernet port(s) can be used for transfer of data and synchronization of user created
data. It is recommended that each device in the system is connected to the Ethernet
network.
No special setup is required for establishing an Ethernet network.
